A beautiful emission nebula in the constellation Cygnus is perhaps my favorite. Captured over several nights in August 2024. Out of town, at a friend's place.

Okay. I'm collecting data for the last night tonight, and it should yield about the same number of hours. But for some reason, I wasn't really feeling the Sulfur data, so I decided to collect Hydrogen and Oxygen instead.

Yes, this one really calls for HOO processing. Essentially, I stacked it as HOO, adding sulfur to the hydrogen.
